TECHNICAL DATA THREE-TERMINAL ADJUSTABLE OUTPUT POSITIVE VOLTAGE REGULATORS KK317 The KK317 is adjustable 3-terminal positive voltage regulator capable of supplying in excess of 1.5 A over an output voltage range of 1.2 V to 37 V. These voltage regulator is exceptionally easy to use and require only two external resistors to set the output voltage. Further, it employ internal current limiting, thermal shutdown and safe area compensation, making them essentially blow-out proof. The KK317 serve a wide variety of applications to make a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the KK 317 series can be used as a precision current requlator.

Changes in Vo due to heating effects must be taken into account separately. Pulse testing with low duty cycle is used. (4) Selected devices with tightened tolerance reference voltage available. (5) Cadj , when used, connected between the adjustment pin and ground. (6) Since Long - Term Stability cannot be measured on each device before shipment, this specification is an engineering estimate of average stability from lot to lot. 2 KK317 CHIP PAD DIAGRAM 2.26 ±0.03 01 06 2.1± 0.03 04 05 03 02 (0,0) Thickness of chip 0,46±0,02 mm PAD LOCATION Pad No Symbol* output adjust output input input output X 0.070 0.070 1.515 2.010 0.875 1.515 Y 1.800 0.090 0.410 0.935 0.760 1.575 01 02 03 04 05 06 Pad size** , mm 0.160x0.195 0.180x0.185 0.190x0.170 0.180x0.205 0.165x0.175 0.190x0.170 * Pads 01, 03, 06 connected in the chip.
